31/18.5R-15LT Pro Street Radial Tire

The Hoosier 31/18.5R-15LT Pro Street Radial Tire (MPN 19350) is a purpose-built radial tire engineered for high-performance street applications where consistent grip and directional stability matter. This 31-inch diameter tire delivers the compound and construction necessary for drivers who demand reliable traction on paved surfaces without the sidewall flex of bias-ply alternatives.

Radial construction distributes load more evenly across the contact patch than traditional bias-ply designs, reducing rolling resistance and heat buildup during sustained driving. The H speed rating indicates a maximum sustained speed capability, while the 2,205-pound maximum load per tire means this fitment suits mid-weight performance vehicles. At 50.5 pounds per tire, the weight is consistent with aggressive street tires in this size class. The directional tread pattern is tuned for forward motion, maximizing water evacuation and edge grip on dry and wet pavement.

The 31x18.5R-15LT sizing places this tire in the light truck category—common on vintage muscle cars, street rods, and modern performance trucks running custom suspension. The black sidewall finish matches traditional street-strip aesthetics. This is the tire for builders who prioritize pavement manners and predictable on-road handling over extreme off-road capability, and who value the engineering heritage of a brand with decades of motorsports tire development.

When selecting a pro street radial, consider your vehicle's actual load distribution, suspension geometry, and intended use—highway cruising versus weekend track time. The Hoosier 31/18.5R-15LT bridges street-driven performance with the durability expected from extended road use, making it a known choice among builders who refuse compromise between show and go.
